Specification of Letters Patent. Patented J l 19 1910 Application filedMarch 6, 1905'. Serial No. 248,570.

{Tole whom it may concern:

''B it; known that I, VALTER J. BARnoN,

n'of the United States, and resident of e borough of Brooklyn, city ofNew York,

in the county of New 'York and State of New York, .have invented certainnew and useful Improvements in Type-VVriting Ma chines, of which thefollowing is a specification.

My invention relates to typewriting machinesand more particularly toindicating mechanism therefor and by which an 1nd1- cator maybeautomatically moved to the indicating position and may be permitted tomore away from the indicating position when desired, withoutdisconnecting the parts, and while the platen remains in the swung-backposition to expose the writing.

To the above and other ends, which will hereinafter appear, my inventionconsists in the features of construction, arrangements of parts andcombination of devices to be hereinafter described and claimed.

In the accompanying drawings, wherein like reference characters indicatecorre 'sponding parts in the various views, Figure 1 is a fragmentaryvertical sectional vlew through the upper portion of a bottom-striketypewriting machine showing one .form of construction embodying myinvention. Fig. 2 is a fragmentary plan view showing the indicatorandj-a portion ofthe actuating means therefor. Fig. 3 is a Viewcorresponding in part to Fig. 1 except that the platen is shown swungback and with the prlnt ing point indicator in the indlcatlng position,the platen being swung back from the lower case position. Fig. 4 is alike view of the same showing the platen swung back from the upper caseposition; Fig. 5 1s a View corresponding to Fig. 4, except that the1ndioator is shown lowered to the normal position byaslight forwardmovement of the 'pla ten framef; Fig. isa fragmentary front I the llaten swung back to expose thewriting an the prmting'point elevation,showin fridic'ator'in thindica'ting position. I {have illustrated my'inventionin the present instanceapplieditoa No. 6 Remington machine,though it should be understood that the inventionlniay be appliedtovarious other, forms of mach nes and that the construction may bechanged accordingly; 1 I

The top plate 1 of the machine suppprts the? usual =lugs er risers 2 fora traverse 5. A platen frame 6 is pivoted, by pivotpins 7, to links orarms 8 that project from a rod or rock shaft 9 pivoted at its ends inthe carnage truck 5. Screw stops 10 and 11 extend in opposite directionsthrough lugs 12 carriedby the truck and cooperate with :the pivot pins.7 to limitthe fore and an movement of the platen frame when it isshifted to shift the platen from one case position to anothef'." Theplaten frame carries a platen 18 and the usual paper apron let, platenscale 15 and feed rollers 16 and 17. The forward end of the platen framecarries a roller 18 that cooperates with a shift rail 19 and by whichthe platen is shifted for upper and lower casewriting and a handle -20is provided to swing the platen frame hack on its pivots.

A bracket plate 21 may be secured place in the rear of the platen by twoscrews is bifurcated at its forward end, and the o arms 2 1 of thebifurcated portion are providedwith upwardly extending arms 24 havlngbearings for a pivot pin 25 of a printing point indicator 26, that inthe present instance has parallel sides and ends with a central openingtherein through which the types strike, and the outer of the indicatorhas. a pointer 27 projecting outwardly therefrom to register with theprinting point and a pointer 28 projecting inwardly therefrom toregister with the indices on the .platenscale .15, a1l as willhereinafter more clearly appear. The prlnt ing point indicator istherefore pivoted in the rear of the platen and in its normal positionextends beneath the platen in substantially a horizontal.-plane. Abearing piece 29 extends inwardly from one of the arms 2% to receive.aflheaded screw 30 that constitutes a pivot for a pivoteddevice orpivoted device 31 contacts with a finger 3-1 that is-inte a1 with andprojects'rearwardly from the indicator 26 which is supported. 1nlts'lowermost, or normal position, by a pin 35 projecting inwardly fromone of the arms 24.

A detachable -two-part collar 36 is mounted to turn freely on a rod 37of the platen frame near each end thereof and each collar carries adepending arm 38, the arms being connected at their lower ends by acrossbar 39 that extends substantially throughout the length of theplaten and cor responds in length substantially to the run of thecarriage. The. upper side of each collar 36 is preferably flattenedforthe attachment of one end or arm of a substantially U-shaped leaf springo'r friction device 40, so that the cross bar, bail or socalled actuator39,- arms 38 thereof, the sleeves 36 and springs or friction devices 40are all connected and are adapted to swing together around the bar 37 ofthe platen frame as a pivot. A segmental-or half round supporting piece41 is secured by a screw 42 next to each of the collars 36, each piece41 being slotted at 41 for the reception of the stem of its screw 42 andextending from each 'of the supporting pieces 41 is an outwardlyprojecting rigid finger or friction device 43 that extends to a positionwhere it will be brought into cooperation with the cooperating frictiondevice ,40 on the actuator when the platen frame is swung back asindicated in Figs. 3, 4 and 6. The screws 42 not only hold the frictiondevices 4143 in place but afi'ord an adjustment thereof around the rod37 so fasI-to regulate t-he engagement flof the fric tio'n device. thecoiiperating. devices 40.

,. In the operation of the device the platen frame may be swung backfrom any point in the travel of the carriage and the friction devices 43which are fixed to and turn wit-h the platen frame will not be broughtinto contact with the cooperating friction devices 40 on the actuatoruntil the lastf portion of the swinging movement of the-{'pl'aten, andduring the first portion of the swinging movement of the platen theindicator will remain at rest in its normal substantially horizontally.disposed position beneath the platen, and the platen frame may, ifdesired, be turned back to inspect the writing without actuating theindicator. When friction devices 43 are brought into contact with thesprings 40 a frictional engagement between the two sets of devices willbe established and the bail, bar or actuator 39 will be swung forward,thus vibrating the lever or device 31 against the tension of its springand the lever 31 cotiperating with the finger 34 will cause theindicator to be automatically moved from the substantially horizontalposition to the upright substantially vertical indicating positionillustrated in Figs. 3, 4 and 6, whether the platen be swung fromtheupper case position, with pivot pins 7 in contact with the stops 10, asillustrated in Fig. 4, or from the lower case position with the pivotpins in contact with the stops 11, as indicated in Fig. 3. After I be acontinued movement of the devices 43 with the platen frame withoutefi'ecting undue pressure on the indicator, there being merely arelative movement efi'ected between the devices 43 and their cooperatingdevices 40. The slightest return movement of the platen will, however,suflice to restore the indicator to the normal position while the platenframe is still maintained in an upright position, as indicated, forinstance, by a movement of the platen frame from the position shown inFi 3to that indicated in Fig. 5. Thus the indicator may be readilyrestored to the normal position beneath the platen where it stands awayfrom the platen to enable an erasure to be readily made with outinterference from the indicator, and while the platen is maintained inthe swun back position with the writing ex )osed and where-an erasurecan be made wit out difiiculty. l urthermore,the indicator can berestored to the normal position without efiecting a disconnectionbetween the platen frame and the indicator so that, if desired, theindicator may immediately be brought to the indicating 1position by aslight backward tilt of the p aten frame. From the foregoin diescriptionit will be understood thatthe oiinectlons between the indicator and theplaten frame constitute differential means or connections whereby theslight forward movement of the platen frame from either of the positionsshown in Fi s. 3 or 4 to that indlcated in Fig. 5 is su c ient to returnthe indicator to the normal position while the platen still remains inthe swung back posltion where the writing can be easily inspected anderasures may be made.

From an inspection of Fig. 4 it will be observed that when the indicatoris in the indicating position the pointer 27 does not contact with thepaper and that the indicator itself rests agalnst the platen scale 15and that during the swinging movement of platen the pointer will not bebrought into contactwith the platen or the paper thereon.

In certain kinds of printing point indicators heretofore devised, andmore particularly those which employ springs to automatically move theindicator to the indicating position when the platen is swung back toexpose the writlng, considerable difliculty has been encountered byreason the indicator contact-in paper and by the sharp end of the I w enguides or paper feed rollers at the front of, the platen during theswinging of the platen to the normal position and at times interferingwith the feed of. the carriage by bear-ing thereon and by coming intocontact with the paper feedin devices during the travel of the carriage.hen againconsiderable diflicnlty has been experienced by with theprinted matter and blurring te imprint on the ointer engaging the paperand mutilating 1t. 13

the present invention these and other (lliib' culties heretoforeencountered in printing point mdicato rs are obv1ated since theindicator remains in the normal position beneath the platen until theplaten frame has almost completed its backward swing and is restored tothe normal position at the first aortion of the forward swing of the)laten rame and when the indicator is in t e indicating po- 'sition itis prevented from coming into contact with the paper by contacting withthe platen scale. While I have described one form ofconstructionembodying .my invention, it should means'between said platenframe and indicator for placing the indicator under control of the latchframe in the swinging movements t ereof, said connecting means includingmeans by which the connecting means are constantly maintained incooperative relation with the platen'frame and indicator when theindicator is in the normal or non-indicating position and the platenframe is inaintamed swung back to expose the writing, whereby theindicator may be moved to the normal position or to the indicatingposition While the platen frame is maintained in the swung back positionand without breaking the operative connection between the platen frameand indicator.
